AMANIDUS M. HEMBERG, OF MINNEAPOLIS, MINNESOTA.

CAR-DOOR.

Application filed April 17, 1915.

To all 'zo/tom t may concern.'

Be it known that l, r-mfrANnUs M. HEM- i-snao, a citizen of the United States, residing at h/iinneapolis, vin the county of Hennepin and State of Minnesota, have invented certain new and useful improvements in Car- Doors; and l do hereby declare the following to be a full, clear, and exact description of the inventimi, such as will enable others skilled in the art to which it appertains to make and use the same.

vly invention has for its object to provide an improved car door which will take the place, not only ot a grain door, but also of an ordinary outside slide door of a boX car.

To the above ends. generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

The invention is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views, Referring to the drawings:

Figure 1 is a view in side elevation showing the central portion ol a bor: car and illustrating one oit my improved car doors applied thereto;

nig. 2 is a vertical section taken on the line m2 x2 on 1; and

Fig. 3 is a horizontal section taken on the line a' m3 on Fig. 1.

The numeral 1 indicates the body of an ordinary box ear, the same having the usual door opening and the customary horizontally extended door supporting track rail 3 secured on the outer side of the car below the eaves and above the door opening and extending to a point considerably at one side of the door opening.

So ar as the broad idea of my invention is concerned, the door may be constructed in dilierent ways, but, as shown, it comprises a main door 4 and a supplemental door 5. This main door 4 is preferably eonstructed from a flat sheet metal or steel plate, which, in width, is considerably wider than the door opening 2, so that it overlaps the door opening, as best shown by full lines in Fig. 3 when the said door is in position to close the door opening. The door 4, when in working position, rests on the floor of the car. The supplemental door 5 is shown as hinged at 6 to the top of the door frame so that it may be swung inward and upward as indicated by dotted lines in Fig. 2, and there held. by any suitable means such, for

example, as by a hook hinged to the car roof. The main door 4 and supplemental ,door 5 have angle iron strips 7 and 8, re-

spectively, attached to their abutting edges, and the outstanding angles of these bars have co-incident perforations through which pins S) may be passed. Car seals, not shown, may be applied, through perforations in the depending ends of the pins 9, when desired. ln its lower portion, the main door 4 is provided with a large discharge port that is normally closed by a l@ate 10 held thereto at its upper edge. As shown, the gate 10, at its lower free edge, has secured thereto, a small reinforced angle bar 11 that, when the said gate is closed, is directly engaged by a lock bar 12 to hold the gate closed. This lock bar 12 is pivoted to the side of the car at one end, as indicated at 13, and, at its other end, it is adapted to be dropped inside of a retaining bracket 14 secured to the same side of the ear, but on the opposite side of the door opening. This lock bar 12 is adapted to be turned into an inoperative position, as shown, by dotted lines in Fig. 1. When it is in its operative position shown by full lines in Fig. 1, it prevents the gate 10 from moving out-ward. Tf desired, this lock bar may be secured in its Voperative position by a car seal suitably applied thereto.

As alreadv indicated, the main door 4 is of such width that it cannot be moved outward through the door opening while in a position parallel to the side of the car. It can, however,be moved outward through the said door opening when moved at an angle to the side of the car. lt is supported 'for such movement by a hanger bracket or arm 15 riveted, or otherwise rigidly secured to the upper central portion thereof, and eX- tending upward and terminating in a swivel socket 16 swiveled on the head of the truck bracket or travel 17 that s equipped with a wheel 18 arranged t0 run on the track 3.

VV hen the door is closed against grain pressure from within the car, the grain pressure may be relieved by opening the gate 10. To open the gate 10, of course, it is first necessary to raise the look bar 12. When the grain runs from the ear sufficiently to aiiord clearance for a slight inward movement of the door 4, the said door is turned into an oblique position, substantially as 1ndicated by dotted lines in Fig. 3, and then may be swung outward through the door opening. The swivel joint connection be,-f

1from rolle'dT-iron or steel.

tween-*the hanger `bracket 15 v'and -truck bracket 17, of course, permits such move-V ments of the door, -VVVhen the doccie-.swung x outside of the door opening, it may be moved along the track 3 until it is carried along the outer side of the car body to a position enti-rely atfone side of the door opening.v

The door Will be held by gravity close against the side of the car.

The door 4: is preferably made of a comparatively thi-nsliee't of steel and is braced and made strong against lateral pressure, by oblique truss bars 1S), preferably formed The numeral 20' indicates a hand piece applied to the out'er'face of thedooi- 4.

""'The door above described, While of comcar.` In Vloading the Acar With' grain, the` inain'y door vvilllrst be' closed and then the carniay` 'beprope'rly "loaded with grain through the openingaiforded above the'main door, and this 'door may Ibe closed only after the grain has been loaded into the car.

i LWhat I claim is:

- The combination with a car body having a door opening, of a car door havingra rigidly and permanently connected body portion that is Wider than said door opening and is seated at its side edges against the inner face of the door frame with freedom for inward lateral swinging movement, a

track extended above said door 'opening' along the outer side ofthe car body, a traveler 'movable on said track, and a' flexible hanger suspendingl said door from said traveler with Jfreedom for ylateral and angular swinging movement in respect to said car body, so that the said door may be moved through said door opening When turned at an angle thereto.

In testimony whereof I ailix my signature in' presence of -tivo 'Witnesses lAl\/lAl\lDUS M. HEMBERG.
